A WebAccess DDE Server allows 3rd Party Software packages to monitor and Acknowledge alarms. Typical applications include pagers and telephone alarm monitoring.
Applications typically access a DDE Server using the following convention:
WebAccess Server's application name: bwddexe
WebAccess Server's topic: topic
WebAccess Server's item: tagname
Tagname is the Tag you want, for example TIC101, ZT-106, speed, etc.
The DDE Client application must have access to the WebAccess SCADA node: the DDE Client application must be running on the SCADA Node PC or have a Network DDE connection (NetDDE) to the SCADA node.
